2 Outline of the presentation The Problem Development of improved rice PBV Objective of study Methodology Findings Conclusions Recommendations The way forward References Acknowledgements 2

3 The Problem Post-harvest losses (waste and spoilage) constitute a major drain on food production and food security in Africa In Ghana, annual losses of cereals are between 20-30% which is mainly attributed to inadequate postharvest practices and technologies (MoFA, 2010). The Northern Region is a major producer of rice in Ghana (37%). Rice produced in the region is mostly parboiled due to harsh climatic conditions(high temperatures and low humidity) 3

4 The Problem cont’d  The widespread use of traditional rice-parboiling technology in Northern Ghana leads to poor quality of final rice which often does not meet consumers’ expectations 4

5 Development of improved rice PBV 5 iPBV(improved parboiling vessel) CPHP 2004 project(FRI and DFID) 2mm in thickness and has two chambers Parboil about max 100 kg of paddy Fuel savings of 30% - 50% Reduced drudgery in the parboiling process Vessel allows uniform heating (Tomlins et al., 2007).

6 Objective of the Study Assess the impact of an improved rice PBV adoption on household income in Northern region of Ghana. 6

7 Methodology 7 ObjectivesDescription of the ObjectiveMethod of analysis Objective oneDescribe the differences in the characteristics of adopters and non adopters households in the Northern region of Ghana. Descriptive statistics such as mean, minimum, maximum, standard deviation, percentages Objective TwoDetermine the factors that influence the adoption of iPBV technology in the Northern region of Ghana. Logit model (Green 2008; Baidu- Forson, 1999; Feder et al., 1985) Objective threeEstimate the impact of the adoption of iPBV technology on the household income in the Northern region of Ghana Propensity score matching(PSM) (Rosenbaum & Rubin, 1983; Becerril & Abdulai,2010;Dehejia & Wahba, 2002) Objective fourDetermine the major constraints faced by parboiling households in the Northern region Kendall’s coefficient of concordance

19 Findings All of respondents were female About 53% were aware of the existence of the technology. Education, Age,member of PBO, contact with developmental organisation, access to credit, targeted communities and high production capacity increases the probability of adopting the iPBV technology Price of paddy, having other occupation, household size,using hired labour and having a lot a experience reduces the probability of adopting iPBV technology 19

20 Findings Adopting the improved rice PBV technology increases the annual household income by 622 GHs The major constraints facing the parboilers were lack of funds, expensive fuel (fire wood) and lack of equipment for parboiling. Distance to milling place, Low storage capacity and weak knowledge of drying operations had minimal impact on their operations 20

21 Conclusion Improved rice PBV technology increases the household income for households who adopted the technology Constraints facing the parboilers were lack of funds, expensive fuel (fire wood) and lack of equipment for parboiling. 21

22 Recommendations Local artisans (such as welders, etc) and other stakeholders should pick up the technology and produce more iPBV with local resources ;this will even reduce the cost of the technology. Also stakeholders should encourage microfinance institutions to support rice parboilers with credit (since they are now creditworthy as a result of using the new technology which increases their incomes). Institution such as FRI, CSIR and Universities should develop alternate source of fuel (such as one the can use rice husk) to reduce the cost of fuel for processing rice. 22

23 The way forward In principle the new technology offer an increase in income to the parboilers but it is expensive; I. More developmental agencies should partner these women in other to acquire more of the technology for the women which has positive impact on their livelihood. II. Microfinance institutions should also be challenge to provide these women with credit at low interest to enable them to purchase this technology as to improve their income. 23
